LIGHTING nnvrcn.

Specification of Letters Patent.

Patented Nov. 26, 1912.

To all whom 'it 'may concern:

Be it known that we, WLADIMIR DANIEK, subject of the Emperor ofAustria-Hungary, resident of Prague, Bohemia, Austria-Hungary,CONSTANTIN ERNovsK, subject of the Emperor of Austria-Hungary, residentof Prague, Bohemia, Austria-Hungary, and GERHARD KLOTH, subject of theKing of Prussia, resident of Treptow, near Berlin, Germany, have jointlyinvented an lmproved Lighting Device, of which the following is aspeciiication.

This invention relates to an improved lighting device particularlyintended for lighting cigars, cigarettes and the like, and of the typein which two parts telescope the one within the other and which can bemovedv relatively to one another so as to open the cover andsimultaneously ignite the wick.

The present'invention has for its object to provide an improvedconstruction of such lighting devices as will be hereinafter fullydescribed and claimed.

In order that the invention may be clearly understood, reference is madeto the accompanying drawings, whereon:

Figure 1 is a vertical section of the light-l ing device, Fig. 2 is aview similar to Fig. 1 showing the lighting device when the parts .arecollapsed so as to open the cover and ignite the wick. Fig. 3 is avertical section at right angles to Fig. 1 and taken on the line A-B ofFig. 1.

Referring to the drawings: The lighting device comprises an outer casingl, to the upper end of which is pivoted at 2 a cover 3, and a fuelreservoir 4 adapted to slide within the outer casing 1. rEhe outercasing 1 is provided externally with projections 5 or with a corrugatedsurface or with both, the projections 5 and the corrugations forming afinger grip whereby the lighting device may be readily manipulated. Itwill of course be understood that the projections 5 or corrugations maypass entirely around the outer casing 1 or may be arranged only onopposite sides of the same and that, if desired, any suitable form offinger-grip may be provided such as a groove or ledge or the like.

The fuel reservoir 4 may be supplied with benzin or the like fuel by wayof an open ing which may be closed by means of a plug,

the fuel reservoir 4 carrying a wicktube 9.

which is adapted to project through a guide 10 formed integral with orsecured to the outer casing 1 and the reservoir 4 being connected to thecover 3 by means of an arm 11 pivoted at both ends, said arm limitingthe downward movement of the reservoir 4 and its upward movement beingcounteracted by means of a spring 12 surrounding the wick tube 9 andbearing at one end against the upper end of the reservoir 4, and at theother end against the guide 10. When the reservoir 4 is pressed into theouter casing l against the action of the spring 12, the wicktube 9slides within the guide 10 and is projected therefrom and brought intoigniting position, at the same time the cover 3 being opened by means ofthe arm 11. 0n the reservoir 4 being released, the spring 12 returns thereservoir 4 to its normal position, atthe same time closing the cover 3and withdrawing the wick tube 9, and as the cover 3 closes, means areprovided for extinguishing the light. Said means comprises a plug 13made integral with or secured to the cover 3, the lower end of said plugbeing conically formed and being adapted to wedge into the open end of arubber or like packing-ring 14 which surrounds the tubular part 15 ofthe guide 10 so that when the cover 3 closes, the plug 13 cuts olf thesupply of air to the wick.

The igniting mechanism comprises a friction wheel 16 rotatably mountedon a spindle 17 carried by an upward extension 18 of the fuel reservoir4, a piece of pyrophoric material 19 being maintained in frictionalcontact with the friction wheel 16. The pyrophoric material which may beof flint or any suitable alloy, such as an alloy of ccrium and iron, isarranged in a compartment 20 supported by t-hc upward extension 18 ofthe reservoir 4, said compartment 20 i reservoir 4, the plate 22 beingthus normally pulled downwardly so as to cause the frog to press thepyrophoric material 19 into constant frictional contact with the wheel16. The plate 22 is provided with an upper extension slotted orotherwise formed at 27 so as to form a hand grip whereby when the cover3 of the lighting device is opened, the plate 22n may be drawn upwardlyagainst the action of the spring 25 and the pyrophoric material 19thereupon released after which the same may be removed or renewed ifrequired.

A pa'wl mechanism is provided for rotating the friction wheel 16, saidpawl mechanism preferably comprising a toothed disk 28 rotatably mountedon the spindle 17 of the friction Wheel 16, the teeth 29 of said disk 28being adapted to engage crownratchet teeth 30 formed on one of the sidefaces of the friction wheel 16, the teeth of the disk 28 and frictionwheel 16 being held in engagement preferably by arching the plate 22 at31, said arch under the action of the spring 25 of the plate 22 forcingthe friction wheel 16 into contact with the disk 28. The disk 28is'provided with a laterally projecting fork 32 the prongs of which areadapted to embrace a pin 33 projecting inwardly from the outer casing 1.The arrangement is such that when the reservoir 4 is pressed upwardlyfrom the position shown in Fig. 1 to that shown in Fig. 2, the disk 28and friction wheel 16 are moved upwardly therewith, and the fork 32 ofthe disk 28 coacting with the pin 33 on the easing 1, the disk 28 ispartially rotated into the position shown in Fig. 2, carrying with itthe friction wheel 16 Vwhich contacting with the pyrophoric material 19causes a spark to be generated which ignites the wick projecting fromthe wick tube 9 which at this moment has been raised above the packingring 14, as shown at Fig. 2. When the benzin reservoir 4 is released,the spring 12 returns the same to its original position together withthe friction wheel 16 and disk 28, the teeth of the latter during thereturn movement of the disk riding over the side face of the frictionwheel 16 and engaging in the next tooth of the latter.

It will be noticed that the arm 11 is so constructed that the latterfully clears the extension 18 of the reservoir 4 when t-he reservoir ispushed upwardly, so that the cover 3 may be fully opened and thereby anypossibility of the latter becoming heated by the flame, is obviatedwhile at the same time ready access is given to the plate 22 for thepurpose of renewal yof thepyrophoric material.

It will be readily understood that in manipulating the lighting device,the thumb is applied beneath the bottom of the fuel reservoir 4, whilethe index and middle fingers are caused to grip the casing 1, thereservoir 4 being forced into the outer casing 1 by pressing the thumbagainst the reservoir while holding the fingers against the projections5. By this arrangement the lighting device can be readily manipulatedand moreover the cover may extend over the whole width of the casing asthecasing is not clasped in the neighborhood of the cover whenmanipulating the device as was heretofore usual.

It will moreover be seen that by the improved light-ing device the wicktube and igniting device are projected above the outer casing and aret-hus surrounded by free air thereby enabling the wick to be readilyignite lt will of course be readily understood that the constructionhereinbefore shown and describedmay be readily varied according torequirements without departing from the essence of the invention.

What we claim is 1. In combination with a lighting device of the typehaving an outer casing, a cover hinged thereto, and a fuel reservoirtelescoping in said outer casing; a wick tube project-ing from saidreservoir, a guide carried by said outer easing and through which saidwick tube slides, and means for igniting the wick.

2. In combination with a lighting device of the type having an outercasing, a cover hinged thereto, and a fuel reservoir telescoping in saidouter casing; a `wick tube projecting from said reservoir, a guidecarried by said outer casing and through which said wick tube slides, anannular packing ring seated on said uide and adapted to surround thewick tu e projecting through said guide, an internal conical plugcarried by said cover and adapted to Wedge in said annular ring when thecover is closed, and means for igniting the Wick.

8. In combination with a lighting device of the type having an outercasing, a cover hinged thereto, and a fuel reservoir telescoping in saidouter casing, a Wick tube projecting from said reservoir, a guide cariedby said outer casing and through which said Wick tube slides and aspring around the Wick tube and tending to maintain said reservoi andouter casing apart, and means for igniting the wick.
